FindThreads
This module determines the thread library of the system.
Imported Targets
This module defines the following IMPORTED target:
- Threads::Threads
- The thread library, if found.
Result Variables
The following variables are set:
- Threads_FOUND
- If a supported thread library was found.
- CMAKE_THREAD_LIBS_INIT
- The thread library to use. This may be empty if the thread functions
are provided by the system libraries and no special flags are needed
to use them.
- CMAKE_USE_WIN32_THREADS_INIT
- If the found thread library is the win32 one.
- CMAKE_USE_PTHREADS_INIT
- If the found thread library is pthread compatible.
- CMAKE_HP_PTHREADS_INIT
- If the found thread library is the HP thread library.
Variables Affecting Behavior
-
THREADS_PREFER_PTHREAD_FLAG
If the use of the -pthread compiler and linker flag is preferred then
the caller can set this variable to TRUE. The compiler flag can only be
used with the imported target. Use of both the imported target as well
as this switch is highly recommended for new code.
This variable has no effect if the system libraries provide the
thread functions, i.e. when CMAKE_THREAD_LIBS_INIT will be empty.
